Quality Control

SRC maintains very strict quality control system. In addition to usual inspection process, such as profile check, roundness, cylindericity, and etc, we check the followings to ensure quality standard.

  1. Microstructure analysis : We analyze the microstructure of coating layer of every roll
  2. Wear resistance Test : On the regular basis we do wear resistance test of tungsten coating layer.
  3. Crown and Paper Feeding Test : We evaluate the amount of crown and line-pressure in the test station where steam is serviced. We also perform paper feeding test to check the runnablity of the rolls.
  4. Shock Resistance Test : On the regular basis we check the shock resistance of the coating, and try to make an improve our coating.
